Folding of the cerebral cortex creates these ridges and grooves which serve to separate brain regions and increase cognitive ability. The superior temporal sulcus is the fissurethat separates the superior and middle temporal gyri. The long, meandering hills (gyri, singular = gyrus) and valleys (sulci, singular = sulcus) provide a greater surface area to the brain. Add to New Playlist. “Heschl’s gyri or Heschl’s convolutions is commonly called as the transverse temporal gyri which are mainly located in the primary auditory cortex that invasively lies within the adjacent sulcus of the brain, covering the 41, 42 Brodmann’s area and characterized as the very first cortical part to be able to process the all incoming auditory signals.” sulci) is a depression or groove in the cerebral cortex. A head on collision, license plates smudging together. The subparietal sulcus or suprasplenial sulcus is a sulcus, or crevice, on the medial surface of each cerebral hemisphere, above the splenium of the corpus callosum.
